Confined field trials (CFTs) are conducted to inform environmental risk assessments that are required by regulatory authorities before genetically engineered crops can be approved and released for cultivation. Many countries expect CFTs to be conducted as a matter of course, even if satisfactory data are already available from trials conducted elsewhere. The scientific basis for requiring duplicative trials is questionable, but policy and perception issues make accepting data from other countries difficult for many regulators.
The primary variable that differentiates CFT locations is agroclimate, which means that data from trials cultivated in like agroclimates should be considered relevant and sufficient to satisfy regulatory requirements, irrespective of the country where the CFTs are conducted.

Global Environmental Zones Explorer (GEnZ)
Since the Agriculture & Food Systems Institute’s publication of a conceptual framework for data transportability in the journal Transgenic Research in 2014, it has continued to make significant effort to progress this work beyond theory to practical application. In particular, our Global Environmental Zones (GEnZ) Explorer is a simple-to-use online tool that allows users to visualize agroclimatic zonations and their relationships to CFT locations.
Transportability of Confined Field Trial Data for Environmental Risk Assessment of Genetically Engineered Plants: A Conceptual Framework
Transgenic Research | April 21, 2014
It is commonly held that confined field trials (CFTs) used to evaluate the potential adverse environmental impacts of a genetically engineered (GE) plant should be conducted in each country where cultivation is intended, even when relevant and potentially sufficient data are already available from studies conducted elsewhere.
